Bilingualism was not the norm in our family tradition, except for distant ancestors who spoke Gaelic. The only language study by immediate family members was of Latin by my parents. In the first year that Japanese was offered at my high school in the 1970's, I was prompted by the teachers to try this new offering. I acquiesced without giving it…

Over the last decade, iterated learning studies have provided compelling evidence for the claim that linguistic structure can emerge from non-structured input, through the process of transmission. However, it is unclear whether individuals differ in their tendency to add structure, an issue with implications for understanding who are the agents of…

This article is the first in a series about teaching statistics. The authors discuss the role of statistics and the difference between mathematics and statistics.

Background: Despite a vast literature linking in-home firearm access to youth suicides, few studies have examined whether and how "gaining" access to household firearms shapes adolescents' development of suicidal ideation. Objective: This study examined whether gaining access to household firearms among U.S. adolescents is associated…

In five experiments, we established and explored the contrast diversity effect--the effect of diversity of negative evidence on inductive inferences drawn from a single observation of a target exemplar. In Experiments 1 through 3, we show that increasing the diversity of negative evidence in a contrasting category led people to infer that a target…

Do all learners make the same restudy decisions, or is there heterogeneity within the population? The present study combines three previously published datasets and uses latent profile analysis to determine if subpopulations of learners can be identified that make different restudy decisions. Based on multiple fit indices, cross-validation, and…

Objective: Female post-secondary students typically engage in less physical activity than their male counterparts. Given that women have greater anxiety sensitivity (ie, fear of arousal-based body sensations) and anxiety sensitivity is inversely related to physical activity participation, this study sought to determine if anxiety sensitivity…

Kim and Opfer (2017) found that number-line estimates increased approximately logarithmically with number when an upper bound (e.g., 100 or 1000) was explicitly marked (bounded condition) and when no upper bound was marked (unbounded condition). Using procedural suggestions from Cohen and Ray (2020), we examined whether this logarithmicity might…

This study is a survey study which aims to determine underlying causes of anger and the anger levels of individuals, in the sample cases and mood-states defined in the research. 255 people participated by filling in forms developed by the researcher. They were asked to rank 6 mood-state expressions between 1 and 6, to classify 23 sample case…

Scams involving university degrees are flourishing in many emerging markets. Using a resume experiment in India, this paper studies the impact of "gray degrees," or potentially bought academic credentials from questionable universities, on callback rates to job applications. The experiment varied the type of degree (no, gray, and…

In this review, findings from studies investigating gender differences in spatial ability, math anxiety, and math achievement, the relationship between spatial ability and math anxiety, between spatial ability and math achievement, and between math anxiety and math achievement are synthesized. As a result of this synthesis, a sequential mediation…

Kim and Opfer (2017) found that number-line estimates increased approximately logarithmically with number when an upper bound (e.g., 100 or 1000) was explicitly marked (bounded condition) and when no upper bound was marked (unbounded condition). Using procedural suggestions from Cohen and Ray (2020), we examined whether this logarithmicity might…

We combine newly released individual data from the 1940 full-count census with death records and other information available in family trees to create the largest individual data to date to study the association between years of schooling and age at death. Conditional on surviving to age 35, one additional year of education is associated with…

Ethical attitudes are especially important for accounting students as they transition from higher education into a profession where continuing education requirements for ethics are pervasive across state boards. We examine if generational categorization impacts ethical attitudes. We compare 172 student responses from an ethical survey to results…

Graduation efficiency is of top concern for institutions of higher education throughout the world. Increasingly, accountability metrics have come under scrutiny as policymakers seek to ensure public resources are efficiently used. Traditionally, higher education policymakers in the USA and Europe have used graduation rate as an accountability…
